“…7). It is a basic mechanism for ensuring train safety: only one train, the one with the token, is permitted to enter the track section between two stations (6) . The token, which is a physical object such as a staff or a tablet, is controlled by the token controllers (one at each station), which communicate by telephone to ensure that only one token exists at a time.…”

“…The implementation of these railway projects depends on reducing the infrastructure cost, and a good way to do this is to reduce the cost of the signalling system (1) (2) . Investigations of telecommunication methods supporting the signalling system (3)- (5) , active train detection systems (6) , and reduced-cost signalling systems such as ERTMS regional (7) have focused on the business benefits and cost reductions. Efficiency in generation and verification of interlocking control table has been improved (8)- (10) .…”

Conventional communication-based train control (CBTC) systems enable the frequent operation of trains by detecting train's position and the telecommunication system between the onboard and trackside controllers compared to traditional signalling systems. However, the railway signalling system is still costly, and the cost of the trackside central controllers is particularly high because high-performance failsafe hardware and software are required to control the many pieces of field equipment. Given this situation, we have proposed a concept for a cost-effective CBTC system that provides functionalities equivalent to those of existing signalling systems by using ring topology information shared among the onboard and switch controllers without trackside central controllers. Its basic mechanism is the circulation of a telegram containing information about the exclusive rights to virtual blocks in turn among the controllers within each controlled section. This mechanism reduces the equipment cost to approximately one-third that of a conventional CBTC system. We have now conducted a feasibility study to verify the practicality of this system and have identified potential problems related to system reliability and transportation capacity. This paper presents solutions to these problems and experimental results to show that the proposed system is technically valid and can be applied to many railway lines.

Ensuring the system safety at all times is most important in railway systems where small failures may result in a large number of casualties and property loss. Although there are various design methods, safety precautions, and recommendations of the railway-related safety standards, sometimes the occurrence of accidents cannot be prevented. In this paper, according to the recommendations of the railway-related safety standards, an interlocking system architecture, which consists of two controllers and a coordinator, for a fixed-block railway signaling system is studied. Based on the Petri net models of railway field components, decision-making strategies including fault diagnosis are presented.

“…Train arrival detection with accelerometers, presented in [5], is used to set of an alarm to warn workers on tracks, being a short-term deployment scenario that uses off-the-shelf accelerometer and communication system. In [6], the need for train detection is motivated, presenting some established train detection systems (e.g. axle counters to count wagons) and giving an outlook on future systems such as ERTMS/ETCS or satellite-based ones.…”

This paper focuses on spotting and classifying complex and sporadic phenomena directly on a sensor node, whereby a relatively long sequence of sensor samples needs to be considered at a time. Using fast feature extraction from streaming data that can be implemented on the sensor nodes, we show that on-sensor event classification can be achieved. This approach is of particular interest for wireless sensor networks as it promises to reduce wireless traffic significantly, as only events need to be transmitted instead of potentially large chunks of inertial data. The presented approach characterizes the essence of an event's signal by combining several simple features on lowcost MEMS inertial data. Using a scenario and real data from vibration signatures generated by passing trains, we show how with this approach the classification of passing trains is possible on miniature nodes placed near the railroad tracks. Experiments show that, at the cost of slightly more local processing, the chosen features produce good train type classification with up to 90% of trains correctly identified.
